Key takeaways:
- The Banff Patellofemoral Instability Instrument 2.0 may assess kinesiophobia and pain catastrophizing after patellofemoral surgery.
- The instrument had significant correlation with patient-reported outcomes.
Published results showed a significant correlation between patient-reported outcomes after patellofemoral surgery and the Banff Patellofemoral Instability Instrument 2.0, which may accurately assess kinesiophobia and pain catastrophizing.
The Banff Patellofemoral Instability Instrument 2.0 (BPII 2.0) is a disease-specific quality of life measure that assesses the physical, emotional and psychological aspects of patient function and recovery before and after surgery for recurrent lateral patellofemoral instability (LPI), according to the study.
“The BPII 2.0 does not explicitly measure kinesiophobia or pain catastrophizing; however, the significant statistical relationship of the [Tampa Scale for Kinesiophobia] TSK-11 and [Pain Catastrophizing Scale] PCS to the BPII 2.0 suggests that this information is being captured and reflected,” Laurie A. Hiemstra, MD, PhD, director of research at Banff Sport Medicine and associate professor in the department of surgery at the University of Calgary, and colleagues wrote in the study.
Hiemstra and colleagues performed a cohort study of 107 consecutive patients (mean age, 25.7 years) who underwent surgery for recurrent LPI between January 2021 and October 2021.
Hiemstra and colleagues aimed to validate the BPII 2.0 with the TSK-11, the PCS and the ACL-Return to Sport after Injury (ACL-RSI) scale. According to the study, all patients had complete scores for all outcomes.
Overall, Hiemstra and colleagues found TSK-11, PCS and ACL-RSI scores significantly correlated with BPII 2.0 scores, which demonstrated higher kinesiophobia and pain catastrophizing scores for this patient population.
“The statistically significant correlations of the BPII 2.0 with kinesiophobia and pain catastrophizing indicate that the BPII 2.0 effectively assessed overlapping constructs of these psychological and emotional aspects of outcomes,” Hiemstra and colleagues wrote in the study. “These results build the criterion and concurrent validity of the BPII 2.0 and the other [patient-reported outcome measures] PROMs in patients with LPI.”
